2×8 Raised Bed Garden Layout: 16 Squares, 9 Crops, With a Plan
A 2×8 raised bed is 16 square feet, two rows of eight squares, and this layout fills it with nine crops: one tomato on a 2×2 block at the west end, one square of cucumbers on a trellis, two peppers, one square of onions, two squares of bush beans, two of carrots, one basil, two squares of lettuce and one of spinach. That is 1 tomato, 2 cucumbers, 2 peppers, 4 onions, 18 beans, 32 carrots, 1 basil, 8 lettuce and 9 spinach plants, 77 in all.

What goes in each square
Read the plan from west to east, the way the planner filled it.
| Crop | Squares | Per square | Plants |
|---|---|---|---|
| Tomato | 4 | 1 per 4 squares | 1, staked or caged |
| Cucumber | 1 | 2 | 2, on a trellis |
| Pepper | 2 | 1 | 2 |
| Onion | 1 | 4 | 4 |
| Beans | 2 | 9 | 18 |
| Carrots | 2 | 16 | 32 |
| Basil | 1 | 1 | 1 |
| Lettuce | 2 | 4 | 8 |
| Spinach | 1 | 9 | 9 |
| Total | 16 | 77 |
The per-square numbers are the planner’s, and they match the square foot gardening chart for every crop but basil. The chart lists basil at 2 to 4 per square for smaller varieties; the planner and my own basil per square foot page put a full-size plant like Genovese at one per square, 12 inches apart, in line with what extension guides recommend. The linked crop pages show the planting pattern for each square.
Why the crops sit where they do
The planner claims the northwest 2×2 block for the tomato before it places anything else. A 2×8 bed is only two squares deep, so that block takes the full width and the tomato fills the west end, both rows. The cucumber is the other climber, and the planner puts climbers on the north row: it takes the first open north square, right beside the tomato. Both carry the trellis icon because both are trellis crops in the planner’s data. With the bed running east to west, a trellis on the north row throws its shade on the path behind the bed, not on the crops in front of it.
Everything else goes in tallest first, filling each 1-foot column from north to south and working east. By the planner’s average heights that order is peppers (36 inches), onions (24), bush beans (18), carrots and basil (12), lettuce (10) and spinach (6). So the bed steps down from the tomato at the west end to the spinach at the east end. Beans and carrots each take a whole column. The peppers and the lettuce are split across two columns because each one started in a column that had a single square left.
Reaching a 2-foot bed from one side or both
Two feet is narrow enough to work from one side. Iowa State University Extension says a bed against a building or fence, reachable from only one side, should be no more than 1 1/2 to 2 feet wide, and beds you can reach from both sides can be 3 to 4 feet wide. University of Minnesota Extension puts the one-sided limit at 2.5 feet. A 2×8 bed fits inside both, so it can run along a fence, a wall or the side of a house and you can still reach every square without stepping in. With a path on both sides, you only reach 1 foot in from each side. If you build two of these beds side by side, Iowa State suggests paths about 3 feet wide, enough for a wheelbarrow or cart.
Width also decides what fits. Every square in a 2×8 bed touches a long side, so there is no middle row to reach over. A crop that needs a 2×2 block, like the tomato here, takes the whole width, and the bed holds four of those blocks end to end. One-square crops stay in their own row, so eight squares can run along the north side and eight along the south. If the fence or wall is on the north side, the layout works as drawn, with the cucumber square against it.
If your bed runs north to south, draw it that way in the planner. For these same crops it moves the climbers to the north end: the cucumber takes the northernmost square and the tomato block sits right behind it.
How much soil a 2×8 bed takes
A 2×8 bed is 16 square feet, so every inch of depth adds 16 divided by 12, or 1.33 cubic feet. Filled 12 inches deep it takes 16 cubic feet, about 0.6 cubic yard (16 divided by 27). The 4×4 layout, which shares seven of these nine crops, says ten to twelve inches of soil is enough for its plan and that carrots want the full twelve so they grow straight; ten inches in this bed is about 13.3 cubic feet. My raised bed soil calculator recommends plain compost over Mel’s Mix, and for a bed deeper than 6 inches, 4 to 6 inches of compost with native soil for the rest. In a 2×8 that is 5.3 to 8 cubic feet of compost.
When to plant them, counted from your last frost
These are the windows the Plan My Garden planner uses for every crop in this bed, in weeks from your average last spring frost. Put your date into the seed starting calendar to turn them into dates, or look up your frost dates by zip code on Plan My Garden’s frost date page.
| Crop | Start indoors | Transplant out | Direct sow | Days to maturity |
|---|---|---|---|---|
| Tomato | 5 to 3 weeks before | 2 to 3 weeks after | n/a | 80 |
| Cucumber | 3 to 1 weeks before | 2 to 3 weeks after | n/a | 60 |
| Pepper | 6 weeks before | 2 to 3 weeks after | n/a | 75 |
| Onion | 12 to 11 weeks before | 4 to 2 weeks before | n/a | 100 |
| Beans | n/a | n/a | 1 to 3 weeks after | 60 |
| Carrots | n/a | n/a | 3 to 2 weeks before | 70 |
| Basil | 5 to 4 weeks before | 3 weeks after | n/a | 60 |
| Lettuce | 8 to 6 weeks before | 4 to 3 weeks before | n/a | 45 |
| Spinach | n/a | n/a | 8 to 1 weeks before | 40 |
Lettuce also does well direct sown; I grow my leaf lettuce that way, sowing it straight in the ground and cutting it leaf by leaf. The before and after split in this table follows frost tolerance. The planner rates onions and lettuce semi-hardy and carrots and spinach hardy, and all four go in before your last frost. The tomato, cucumber, peppers, beans and basil are rated tender, and all five wait until after it.
What comes out first
Spinach (40 days) and lettuce (45 days) are the first harvests from this bed. I pick spinach outer leaves as soon as they are hand-sized, and pick lettuce the same way or cut the head at the base so it grows a second one. I pick my bush beans every two days once they start and sow a new square every three weeks to keep them coming. My basil per square foot page cites Illinois Extension’s method: cut the stem just above a pair of leaves so the plant keeps branching instead of flowering, which turns it woody and bitter; basil is frost-tender, so plan to finish picking it before your first fall frost. I pick cucumbers before they fatten and stripe, and start a second set of plants in early summer since production slows in late summer no matter what. The onions, at 100 days, hold their square the longest.
Build this bed in Plan My Garden
Plan My Garden is free to start: enter your zip code, draw a 2×8 bed (or your own size), pick your crops, and it places each plant at square-foot spacing and builds a planting schedule, with start indoors, transplant and direct sow dates, from your zip code’s frost dates.
Seed for this bed
Wood Prairie Family Farm sells certified organic seed from its family farm in Maine, and it carries all nine crops in this bed: tomatoes, cucumbers, peppers, onions, beans, carrots, basil, lettuce and spinach. Provider is the bush bean I grow myself, and Genovese is the basil variety on my own per square foot page; Wood Prairie lists organic seed for both. Code PMG5 takes 5 percent off. Buying through these links supports this site at no cost to you.
Quick questions
How many plants fit in a 2×8 raised bed?
With square foot spacing, 16 squares hold anywhere from 4 unpruned tomatoes to 256 carrots. This mixed layout holds 77 plants across nine crops, including 32 carrots, 18 bush beans and 9 spinach.
How many tomato plants fit in a 2×8 raised bed?
Four if they grow unpruned, one per 2×2 block, and each block takes the full width of the bed. Pruned to a single stem and grown up a string or stake, a tomato fits in one square, so up to 16. This layout uses one tomato block and gives the rest of the bed to other crops.
How many pepper plants fit in a 2×8 raised bed?
Up to 16, one per square, bell and hot peppers alike. This layout has 2, placed right after the tomato and cucumber because peppers are the tallest crop left.
How many cucumber plants fit in a 2×8 raised bed?
Two per square, grown up a trellis. The planner puts climbers on the north row, so a full north row of 8 squares holds up to 16 cucumber plants. This layout has one square, 2 plants.
How much soil do you need for a 2×8 raised bed?
16 cubic feet fills it 12 inches deep, about 0.6 cubic yard. At 10 inches deep it takes about 13.3 cubic feet.
